WINDMILL.

SPECIFICATION forming part of Letters Patent No. 71 1,140, dated October14, 1902.

Application filed April 25, 1902.

T0 all whom it may concern:

Be it known that I, CLINTON WELLS, acitizen of the United States,residing at Seibert,- in the county of Kit Carson and State of Colorado,have invented certain new and useful Improvements in Windmills; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and -use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specication.

This invention relates to windmills.

The object of the invention is to construct an improved drivingmechanism to communicate and convert the motion of the wheelshaft to thepump-rod.

A further object is to construct an` improved brake mechanism to stopthe motion of the wheel when it is thrown out of the wind. f l

A further object is to construct an improved turn-table on which thedriving parts are mounted.V

A further object is to generally simplify and improve the constructionof windmills, involving the use of an eccentric on the wheelshaft, whichcommunicates motion toza sliding block supported by a suitable guide onlthe turn-table and to which block the pumprod is attached. Y'

In the accompanying drawings, Figurel is a perspective View of one sideofthe windmill, and Fig. 2 is a perspective view of the other side. Fig.3 is a detail showing the shaft and eccentric attachment. Y

Referring more specifically to the drawings, the standards of the towerare indicated at 6, to the top of which is bolted or otherwise secured abed-plate 7, on which the turn-table 8 is mounted and rotates. Thebed-plate has a central circular recess which receives the turn-tableandan undercut groove (indicated at 7a) into which projects an annularIiange 8 on the turn-table. The groove of the bedplate is preferablyformed by a split ring 7 b, which is bolted to the top of the bed-plateproper. By removing the ring the turn-table may be unshipped. The endsof the halves of the split ring are joined by plates 7 c, which SerialNo. 104,941. (No model.)

overlap the ends and sides of the halves and are lirmly secured by thebolts.

An arch is indicated at 9, the front and rear pillars (indicated at 9aand 9") of which rise `ferent distances from its periphery, and theshaft may be keyed in any one'of these openings'to vary the throw of theeccentric. A weight 10b is secured to one of the arms of the -wheelopposite the point of greatest eccentricity of the eccentric, and saidweight serves to balance the wheel and insure a steady motion thereofirrespective of the direction of throw of the eccentric. Y

. A vertical guide-post 12 extends from the center of the turn-table tothe top of the arch.

-This post is preferably rectangular in` form and forms a guideon whichslides the reciprocating block 13, to which`the pump-rod 14 is attached.The eccentric Works in a recess formed in the face of the sliding blockVand gives the block an up-and-down motion as the eccentric revolves.The pump -yrod passes through an opening in the turn-table and isprovided below the turn-table with a swiveling joint 14E, which is odsetsufficient to bring it directly below the axis of the turntable. This isnecessary, because-the pumprodextends through the turn-table to one sideof the center thereof.

The vane is indicated at 15,'pivoted to brackets 15, projecting from therear pillar. The vane is turned to throw the wheel out of the wind bymeans of a chain 16, which is connected to the vane and extends througha transverse opening 16, formed in the rear pillar,and thence downthrough a hole in the turn-table to the bottom of the tower in yaposition to be operated by hand in the usual manner. The opening 1-6'ispreferably provided with a bushing or tubev which extends laterally to asufficient distance to give a side purchase on the vane when the chainis pulled. The vane is normally held in the axis of the wheel-shaft by aspring 17 ,which is fixed at one end to the rear pillar and ex- IOOtends Linder a strap l5, secured to the vane. When the vane is turned,the spring bends and draws through the strap. When the chain isreleased, the force of the spring returns the Vane to its formerposition.

A brake-block is indicated at 18 and is the reciprocating block,efectually braking the same. The side of the reciprocating block and theengaging face of the brakeblock are provided with shallow teeth, asindicated at 19, for the purpose of assisting the clamping operation.The teeth are made shallow and rounded, so thata certain amount of slipis allowed to prevent the wheel from stopping too suddenly.

By the construction shown a wide bearing is formed for the turn-table.upon the bed-plate with little or no danger of pinching or binding. Theconstruction permits the mill to be readily setup or taken down from thetop of the tower.

The bearing-surfaces in the reciprocating block against which theeccentric works are preferably inclined and slightly concaved to readilytake the lifting thrust of the eccentric and to prevent any side draft.

The brake is positive in its action and so simple that it will notreadily get out of order.

"What I claim is- It rests solidly' l. In a windmill, the combinationwith a turn-table, of a vertical guide, a block slidable on the guide, awheel, means to communicate motion from the wheel to the block, aswinging vane, and a vane-actuated brake engaging the block.

2. In a windmill, the combination with a vertically-reciprocating blockand means to drive the same, and a swinging vane, of a Vane-actuatedbrake-block engaging the said block to clamp the same when the vane isswung to throw the wheel out of the wind.

3. In a windmill, the combination with a Wheel, a reciprocating block towhich the pump-rod is attached, means to communicate motion from thewheel to the block,and a swinging vane, of a brake-block carried by thevane into contact with the sliding block when the wheel is thrown out ofthe wind.

4. In a windmill, the combination with a turn-table, of an archsupported thereon, a vertical guide within the arch, a reciprocatingblock sliding on the guide, a pump-rod attached to the block, awheel-shaft extending through one pillar ofi' the arch and having aneccentric at the inner end thereof engaging the block, a vane pivoted tothe other pillar of the arch,and a vane-actuated brakeblock pivotedadjacent the reciprocating block.

In testimony whereof I affix my signature in presence of two witnesses.
